METHOD OF WAXING PAPER.

srnorn'zcnrron forming part of Letters Patent No. 286,403, dated October9, 1883.

Application filed September 10,1883. (No model! In all whom it mayconcern.-

Be it known that 1, JAMES B. DUKE, a citizen of the U nited States,residing at Durham, in the county of Durham andState of North Carolina,have invented new and useful Imuse for cigarettes is so light of textureand so extremely delicate in texture that it is readily disintegratedand broken down by the action I vof the saliva, causing awaste of thetobacco in the filler, which is left in the mouth of the smoker. Variousmeans have been devised to avoid this difficulty, such as coating orsat-urating the paper with an impervious and neutral substahce-such aswax or parafline, and other substances-and it is the purpose of myinvention to provide a novel and simple method whereby thecigarette-wrapper, or the sheet from which the wrappers are out,

, may be treated for the purpose of applying thereto a coating of thekind described.

To this end therefore my invention consists in a novel method. ofapplying to the end or ends of cigarette-wrappeis a moisture-proofcoating, consisting of melted waX or parafiiue, or other equivalentmaterial, whereby an impervious and insoluble coating is imparted to thepaper.

The drawings hereto annexed show one form of apparatus by which I maycarry out my in vention, and in said drawings Figure 1 is a plan view.Fig. 2 is a side elevation. Fig. 3 is a transverse section. Fig. 4 is aview of a cigarette-wrapper after it has been treatedhy my method.

A in said drawings designates a coil or equivalent arrangement ofsteam-pipes of suitable form and dimensions, the pipes being arrangedside by side in the horizontal plane. Resting upon this coil is a pan orsimilar vessel, B, adapted to contain paraffine, white wax, or anequivalent substance, which is kept in a fluid condition by the heatderived from the coil.

i Mounted upon a section of the steam-pipe A, which extends in front orat one side of the trough, is a metallic sleeve, 0, preferably made ofmetal having a high conducting-power. The upper face of this sleeve isflattened, as shown at D, a .rib or feather, (2, formed upon the rearside, rising above the flat surface B, and a groove or channel, 0, beingout along its opposite edge, as shown in the sectional view, Fig. 3,leaving a sharp angle, f, which bounds the surface B in front.

In the wall of the pan B, near its bottom line, is placed anoutlet-cock, 1*], of any suit able form, and below the same is placedacon ductor, F, having its'discharge end just above the surface 1). Thisdevice may be arranged near one end of said surface, in which case thepipe-section should be slightly inclined. A dllP-CUP,Gr, is placedbeneath the sleeve C.

With this form of apparatus my method is practiced in the followingmanner: By opening the cock E a limited flow of the melted paraffine orwax is p ermit-t-ed, which, by means of the conductor F, passes slowlyto the fiat surface 1), the rib d aftbrding a gage, which fixes andequalizes the portion of the wrapper treated. The hot melted wax orparaffine is immediately absorbed by the paper, and solidi iiesimmediately upon removal, leaving a colorless, fiexible, and perfectlyneutral coating upon the end of the wrapper, the edge f serving to limitthe application of the paraffine, and to give a straight clean cut lineof demarcation between the coated and the uncoated portions.

It is evident that an entire sheet of paper may be treated by thismethod and afterward cut up into wrappers.

I make no claim, in the present case, upon the apparatus shown anddescribed, as that forms the subject of a separate application.

It is evident, moreover, that the method described can be practiced withother forms of apparatus. For example, the sleeve 0 may be dispensedwith, and in place thereof I may use a plate heated by any suitablemeans. The vessel B also may be heated in a variety of ways, and theconductor F may be of any length within practical limits.

Both ends of the cigarette-wrapper may, if desired, be coated in themanner set forth.

Having thus described my invention, what I claim is 1. The method hereindescribed of preparing the end or ends of a cigarette-wrapper to preventit from being dissolved and broken down by the lips, said methodconsisting in diffusing melted paraffine or wax upon a heated metallicsurface, having a suitable gage, and laying the end of the wrapper, orthe edge of the sheet upon said surface, and immediately removing it andallowing the adherent mate rial to cool, substantially as described.

2. The method set forth of applying melted wax, paraffine, and similarsubstances to the end or ends of a cigarettewrapper, or the edges of asheet, said method consisting in melting paraffine or wax in a suitablevessel,
